It’s safe to say that I’ve gotten into the habit of paying attention to what Boston musicians Sophia Cacciola and Michael J. Epstein — both of the bands Do Not Forsake Me Oh My Darling and The Michael J. Epstein Memorial Library — get up to. Sometimes, you just know when people are going to lead you to cool stuff … such as Do Not Forsake Me’s music video that was a shot-for-shot remake of “The Prisoner,” or the pair’s recent movie, “Ten,” which I had the privilege to see a preview screening of in Cambridge.

So when Cacciola posted on Facebook that she was playing Lucy Moran from “Twin Peaks” in the new Hallelujah The Hills music video, you can bet I went to watch the video immediately. And I’m glad I did, because not only is it entertaining to watch, the song “Confessions of an Ex-Ghost” absolutely kicks.

It’s a relatively straightforward little rocker, with almost no dead space, and the melody is remarkably upbeat considering the lyrics are peppered with dark lines such as “you lost hope when you read my obituary.” All told, this song’s a real keeper, and not just because the video’s delightful.

In a sort-of similar vein, the latest from Frightened Rabbit, “Radio Silence,” uses the same sort of indie-rock-vibrancy-on-the-edge-of-despair, albeit with a great deal more melancholy in the vocals.

This is a lovely little song. It’s sad, but also strangely hopeful, in its strange way. In a lot of ways, it’s a fairly conventional portrait of waiting for someone to call, and is tinged with the distinct air of that call never coming. But still, there’s something of a hope-against-hope in the vocals that makes you kind of root for the persona, makes you believe that he might beat what seems like insurmountable odds. Besides, lines such as “one last kiss on a faceless street/and radio silence” cut with a knifelike beauty.

Lastly, there’s a new song out from the Brooklyn electro-pop outfit, Au Revoir Simone.

The song, called simply “Crazy,” puts the all-female trio’s vocals to great use, evoking a California surf feel that rests surprisingly naturally in the cradle of the synthetic pop music. But as with Frightened Rabbit’s “Radio Silence,” there’s a melancholy about the whole thing, one that seems to weigh down the deceptively upbeat chorus of “Ooh, you girls you drive me crazy” and the sparsely painted picture of bad relationships that someone can’t bring themselves to leave. It’s definitely an end of summer song, basking in the warmth and light, even as it becomes impossible to ignore that dark is coming more and more quickly. (Victor D. Infante)
